Question

If one mole of carbon atoms
weighs 12 grams, what is the
mass (in grams) of 1 atom of
carbon?​

Answer 1

Explanation:

1 mole weighs = 12 g

6.022 × 10^23 atoms weigh = 12g (1 mole = 6.022×10^23)

Therefore, 1 atom weighs = 12 / 6.022×10^23 = 2 × 10^-23 grams (calculation is approximate)

Answer 2

Answer:

So, we know that a mole of carbon contains 6.022×1023 atoms. Therefore, we can write the mass of 6.022×1023 atoms = 12 g. Hence, the mass in grams of 1 atom of carbon is 1.993×10−23g .
